The human brain
Lecture coverage and references
1909-04-19 notes from memory by Mathilde Scholl (in GA264)
Gabriel was the one who, in the 16th century, prepared the human brain through selected births so that an organ was formed therein (to be sure, not perceptible to investigation by natural science), which nevertheless makes the present-day brain appear different from that of a person of the 13th or 14th centuries.
The human brain has undergone a distinct change since the 16th century and has the purpose of enabling humanity eventually to understand Christianity in its full significance.
as a result of the preparation accomplished by Gabriel in the 16th century, of a new organ in the frontal globe of the human brain, it became possible during the last third of the 19th century for what we call spiritual science to be infused by the White Lodge so that the significance of the Mystery of Golgotha could be brought home to humanity in all its implications. When a person now crosses the threshold at earth it is possible for each human being to discover his or her own great Master, now available to anyone in a living physical body who seeks him.
The human brain floats in cerebral fluid and due to its etheric functioning and nature has a strong upwards lifting force. This is why a brain of say 1500 gram only weights about 20 gram in a living human being, this upthrust is an example of the etheric forces.
